Abstract:
A rotary table includes: a stage; a rotary base configured to be rotated around a rotation center axis; a support mechanism that is disposed on the rotary base and supports the stage; a leveling adjustment mechanism configured to perform a leveling adjustment of the stage; and a transfer mechanism configured to transfer a rotative force of the rotary base to the stage. The transfer mechanism includes: an annular transfer member configured to receive the support mechanism therethrough; a first connecting mechanism that connects the transfer member and the rotary base and is rotatable around the first axis; and a second connecting mechanism that connects the transfer member and the stage and is rotatable around a second axis defined in a direction intersecting the first axis.
